Examining the integrated influence of fairness and quality on learners’ satisfaction and Web‐based learning continuance intention

Abstract: . As with any other information system (IS), the success of Web-based learning depends largely on user satisfaction and other factors that eventually increase users’ intentions to continue using the service (continuance intention). This research integrates the IS success model and fairness theory to construct a model for investigating the motivations behind learners’ intentions to continue using Web-based learning. Our model theorizes that the three dimensions of quality (i.e. information, system and service) and the three dimensions of fairness (i.e. distributive, procedural and interactional) affect learners’ satisfaction. We also argue that satisfaction and the three dimensions of fairness will influence learners’ intention to continue using Web-based learning. The hypothesized model is validated empirically using data collected from 289 learners of a Web-based learning service. The results show that information quality, system quality, system use, distributive fairness and interactional fairness exhibit significant positive effects on satisfaction. Also, procedural fairness and satisfaction play significant roles in shaping learners’ intention to continue using Web-based learning.

The Effects of Tourism on Economic Growth and CO2 Emissions A Comparison between Developed and Developing Economies

Abstract: This study empirically examines the dynamic relationships among tourism, economic growth, and CO2 emissions and compares the effects of tourism on economic growth and CO2 emissions between developed and developing economies. By employing robust panel econometric techniques, the results show that tourism has significant positive impacts on economic growth for both developed and developing economies, supporting the prevailing hypothesis of tourism-led economic growth. The results also reveal that the impact of tourism on CO2 emissions is reducing much faster in developed economies than in developing economies, providing evidence of the environmental Kuznets curve (EKC) hypothesis on the link between tourism growth and CO2 emissions. Our findings demonstrate the importance of the classification of countries by economic development level to obtain a deeper understanding of relationships among tourism, economic growth, and CO2 emissions. Policy implications are provided and discussed.

An observer-based approach for chaotic synchronization with applications to secure communications

Abstract: In this paper a systematic approach, based on the linear-state-observer design for constructing two chaotically synchronized systems, is developed. The proposed method is then applied to suggest a means to secure communications. The method combines chaotic masking and chaotic modulation, where the information signal is injected into the transmitter and simultaneously transmitted to the receiver. Furthermore, two well-known chaotic systems, Rossler and Lorenz, and a hyperchaotic Rossler system are considered as illustrative examples to demonstrate the effectiveness of the proposed approach.
